How to Reconstitute P21 5mg

Reconstitution should be performed according to the research protocol. Researchers should confirm the batch-specific peptide amount before preparing any solution.

Basic formula:

Concentration (mg/mL) = Peptide mass (mg) ÷ Reconstitution volume (mL)

Example: A 5mg vial reconstituted with 2mL solvent creates a 2.5mg/mL solution.

For full calculation help, read our Calculating Reconstitution Concentrations Guide. For general laboratory solution calculations, see the Sigma-Aldrich solution dilution calculator.

Bacteriostatic Water for Peptides

Bacteriostatic water for peptides is often discussed in research settings because it contains a preservative. Sterile water does not contain a preservative and is usually better suited for immediate or single-use preparation.

Before choosing a solvent, researchers should review the research protocol, compatibility requirements, and storage plan. Read our Bacteriostatic vs Sterile Water Comparison.

Storage Guidelines

• Store lyophilized powder sealed and dry
• Protect from light and moisture
• Keep cold for long-term storage
• Use sterile handling after reconstitution
• Avoid repeated freeze-thaw cycles
• Label aliquots with concentration and date
